Hi all,

I'm quite new to Infragistics.

Could you pls help my issue below.

I have Infragistics tree created, however when i add event for Node clicked or Selection changed, whenever I clicked on the tree node itself, the tree will disappear.

However whenever i removed the code behind event for node clicked or selection changed, whenever i clicked on the node, the tree did not disappear.

How to add event for node clicked, without making the tree disappear?

Here's my aspx code

<ignav:UltraWebTree id="AITree" runat="server" Width="400px" Height="400px" LoadOnDemand="ManualSmartCallbacks"
        Font-Names="Verdana" Font-Size="8pt" EnableViewState="False" CompactRendering="False" ExpandImage="images/ig_treeXPPlus.gif"
        CollapseImage="images/ig_treeXPMinus.gif" WebTreeTarget="ClassicTree" ForeColor="Black" BorderColor="Pink"
        BorderStyle="None" Indentation="20" Cursor="Default" BackImageUrl="" DefaultImage="" DefaultIslandClass="" DefaultItemClass="" DefaultSelectedImage="" DisabledClass="" FileUrl="" HiliteClass="" HoverClass="" JavaScriptFilename="" JavaScriptFileNameCommon="" LeafNodeImageUrl="" NodeEditClass="" ParentNodeImageUrl="" RootNodeImageUrl="" TargetFrame="" TargetUrl="" ExpandOnClick="True" AllowDrag="True" AllowDrop="True">
        <SelectedNodeStyle Cursor="Hand" ForeColor="White" BackColor="DarkBlue" CssClass="SelectClass"></SelectedNodeStyle>
        <HoverNodeStyle Cursor="Hand" CssClass="Hover"></HoverNodeStyle>
        <NodePaddings Left="5px"></NodePaddings>
        <Padding Top="10px"></Padding>
        <Levels>
            <ignav:Level Index="0" CheckboxColumnName="" ColumnName="" ImageColumnName="" LevelClass="" LevelHiliteClass="" LevelHoverClass="" LevelImage="" LevelIslandClass="" LevelKeyField="" RelationName="" TargetFrameName="" TargetUrlName=""></ignav:Level>
            <ignav:Level Index="1" CheckboxColumnName="" ColumnName="" ImageColumnName="" LevelClass="" LevelHiliteClass="" LevelHoverClass="" LevelImage="" LevelIslandClass="" LevelKeyField="" RelationName="" TargetFrameName="" TargetUrlName=""></ignav:Level>
        </Levels>
        <NodeMargins Top="2px"></NodeMargins>
        <Styles>
            <ignav:Style BackColor="OldLace" CssClass="HiliteClass" Cursor="Hand" ForeColor="Black">
            </ignav:Style>
            <ignav:Style BackColor="Gainsboro" BorderColor="DarkGray" BorderStyle="Solid" BorderWidth="1px"
                CssClass="Hover">
                <Padding Bottom="2px" Left="2px" Right="2px" Top="2px" />
            </ignav:Style>
            <ignav:Style BackColor="#333333" CssClass="SelectClass" ForeColor="White">
                <Padding Bottom="2px" Left="2px" Right="2px" Top="2px" />
            </ignav:Style>
        </Styles>
        <ClientSideEvents />
    </ignav:UltraWebTree>

My code behind

Protected Sub AITree_NodeSelectionChanged(ByVal sender As System.Object, ByVal e As Infragistics.WebUI.UltraWebNavigator.WebTreeNodeEventArgs) Handles AITree.NodeSelectionChanged
            Response.Write("test")
    End Sub

Another question:

How can we call .NET code from the javascript client-side??

Thanks!
